The tariff on imported solar panels strikes me as an intentional sabotage of renewable energy in favor of fossil fuels. The tariff will tip the scale in favor of natural gas by making solar installations for utility-scale power less competitive.

Actual manufacture of solar panels accounts for few American jobs, but President Trump can boast about them while ignoring the loss of far more jobs in the solar power supply chain and installation.

Like Gov. Andrew Cuomo in New York, Gov. Jerry Brown in California and others, governors must take their own actions to counter Mr. Trump’s bad energy policies. Solar power sabotage is only the latest.
